Abstract

Masks are typically made of plastic materials, which can contribute to plastic pollution if not properly disposed. A survey

should be conducted to assess the public awareness of microplastics (MP) emissions and mask disposal, which could inform

targeted educational campaigns to promote sustainable practices. This study used an online survey to gather data from a

sample of the general public aged 20 years or older who had used masks. The survey included questions on mask usage,

disposal, and awareness of the presence of MP in masks. The survey found that, although awareness of the risks of MP was

high, the respondents’ understanding of them was low, particularly among younger individuals. The survey also revealed that

more than half of the respondents did not know whether their masks contained plastic materials and that there was a lack of

awareness regarding the potential environmental and health impacts of improper mask disposal. These results revealed that

it is crucial to raise public awareness of the environmental and health impacts of improper mask disposal and the presence

of MP in masks.
